Model 30.000 - Grading Machines

For models 30.000, the steel, rubber-protected riddles consist of two parts. After removing a single bolt, the riddles can be slid in or out of the riddle box, sideways. This simple action can be carried out on either side of the machine. Elongated tubers that get stuck in the riddles are lifted out of the riddles by the dual-automatic riddle cleaner.
